WALTER IVE. TROLL, OF BALTIMORE, MARYLAND.

OIL-BURNER, TIP.

1 16$ Specification of Letters Patent.

Application filed October 6, 1915.

2"0 ZZ whom it may concern Be it known that I, -WALTER M. TROLL, acitizen of the United States, and a resident of the city of Baltimoreand State of lvifaryland, have invented a new and useful improvement inOil-Burner Tips, of which the following is a specification.

My invention relates to oil burner tips wherein a double channeled bodyportion having opposed outlets provided with concave seats operates inconjunction with alined abutting tubular burner tips having convex endsarranged to be rigidly secured within said seats; and the objects of myin vention are first,.to provide an oil burner tip adapted to preventthe mixture of oil and steam preceding their emergence from the tips;second, to provide an oil burner tip having interchangeable parts whichmay be easily and readily removed or interchanged; third, to providemeans for preventing the steam and oil apertures from being distorted byexpansion of the parts due to heat; fourth, to provide an improved c oilburner having leak proof joints between the tips and body; fifth, toprovide an improved oil burner having the above features and one whichmay be simple and cheap of construction and operation.

I accomplish these several features by means of the preferred form oftheinvention disclosed in the drawings forming a part of the presentspecification wherein like characters of reference are used to designatesimilar parts throughout the said specification and drawings, and inwhieh- Figure 1 is a longitudinal sectional view of a burner disclosingthe manner in which the tips are secured thereto. Fig. 2 is an enlargedbroken vertical sectional view of one tip and a portion of the burner,and Fig. 3 is a plan view, on an enlarged scale, of one of the tips andthe nut which secures the same to the body of the burner.

The present state of the art discloses drooling burners similar inoperation and construction to the present invention except that suchburners are provided with a one piece tip having two apertures therein,for the discharge of oil and steam respectively, and a partition withinthe tip and between the said apertures. In order to avoid leakage, thelength of the tip must be exactly equal to the distance between theseats of the opposed outlets. When this tip is in position and theburner in operation the e:-:-

pansion due to the heat has a tendency to separate the ends of. the unittip from the seats, thereby causing a leakage and permitting the mixtureof oil and steam in an improper manner before leaving the burner tip. Afurther disadvantage of the present type is that the integral tip mustbe replaced in its entirety when the steamapertures wear out and whilethe oil aperture is still in good condition and still serviceable,thereby causing an expensive waste ofv parts.

I propose to avoid the above disadvantages and provide an improvedsimple and cheap construction wherein the oil and steam tips may beadjusted or renewed independently of each other and may be easily andreadily removed for cleansing purposes by means of the device which maybe described as follows Referring to the drawings, the numeral 1 is usedto designate a body portion having double channels 2 and 3 therein forthe passage of oil and steam respectively. The channels 2 and 3 areprovided with opposed outlets i and 5 respectively having arcuateconcave seats 6 and 7, the radius of said arcuate portions being equalto approximately one-half of the distance between the said seats, viz;the arcuate concave seats 6 and 7 conform to opposite portions of asphere whose center coincides with a point midway between said seats.

Seated within the arcuate concave seats 6 and 7 are the convex ends 8and 9 of the hollow or tubular tips 10 and 11 respectively. The tips 10and 11 are alined and have closed abutting endswith suitable apertures13 and 14 for the discharge of oil and steam respectively.

The combined length of the tips 10 and 11 is equal to the distancebetween the seats 6 and 7 respectively, and the surfaces of the arCuateconveX'ends 8 and 9, when the said tips 10 and 11 are abutting, conformto opposite portions of a sphere whose center coincides with a pointmidway between the arcuate seats 6 and 7 of the opposed oil and steamoutlets. so that the said tips may be rotated on said center, into'andout of engagement with said seats as indicated in dotted lines in Fig. lof the drawings.

The tips 10 and 11 are rigidly secured to their respective seats bymeans of union couplings 15 and 16 which are adapted to engage theflanged convex ends 8 and 9 thereof and the bifurcated ends of the bodythe body portion 1 and the alined'abutting tipsare partially rotated ona point coincident with their junction, as indicated in dotted lines inFig. 1 of the drawings, until the convex flanged ends Sand 9 havebeenremoved from their respective arcuate con- I cave seats 6 and 7 whenthe said tips may be'easily removed or interchanged.

' It is obvious from the above-that any eX- pansion due'to' the heatwhich might tend to separate the bifurcated ends of the body portion 1and theseats or outlets therein will merely cause a slight separation ofthe adjacent ends of the burner tips 10 and 11,

withoutstraining any joints or apertures.

It 15 also evident that I have provided an improved burner tip whereinthe said tips may be easily and readily removed and renewedindependently of each other as well as an eflicient and cheapconstruction.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. An oil burner tip comprising a doublechanneled body portion having opposed outlets to the channels therein; apair oftubular burner tips each having a suitable aperture therein forthe discharge of oil and steam respectively, seated within the opposedoutlets; and means adapted to secure each tip to its respective outlet.

,2. An oil burner tip comprising a double channeled body portion havingopposed outlets to thechannel therein, each outlet being provided with aconcave seat; apair of tubular burner tips each having a suitableaperture therein for the discharge of oil and steam respectively andconvex ends adapted to engage the concaveseats of the opposed outlets;and means adapted to retain each tip within its respective seat. 7

3. An oil burner tip comprising a double channeled body portion havingopposed outlets to the channels therein, each outlet being provided witha concave seat; a pair of alined burner tips arranged between theoutlets, each tip having one end thereof closed,

and a suitable aperture near said closed end for the discharge of steamand oil respectively, the other end of each tip being convex and adaptedto seat in the concave seat of .its respective outlet; and suitablemeans adapted to retain each tip within its respec tive seat.

4. An oil burner comprising a double channeled body portion havingopposed outlets to the channels therein, each outlet having an arcuateconcave seat, the radius of the arc uate portion of each seat beingequal tovone-half the distance between said seats; a pair of alinedhollow burner tips arranged between the seats, said tips having closedabutting ends and suitable apertures near said closed ends for thedischarge of steam and oil respectively, the opposite ends of said tipsbeing convex and adapted to seat within the concave seats of the opposedoutlets, the combined lengths of said tips being approximately equal tothe distance between the arcuate seats of the opposed outlets; and meansadapted to retain each tip within its respective seat.

5. An oil burner comprising a double channeled body portion havingopposed outlets to the channels therein, each opposedends of said tipsbeing provided with convex flanges adapted to seat within the opposedoutlets, the combined length of said tips being equal to the distancebetween the seats; and means adapted to engage the convex flanges of thetips and retain the same onto the concave seats.

In witness whereof I hereunto set my signature.
